Chimiro che amicrostrip antennakazhinji ine dielectric substrate, radiator uye pasi ndiro. Ukobvu hwe dielectric substrate idiki zvakanyanya pane wavelength. Iyo yakaonda simbi yesimbi iri pasi pe substrate yakabatanidzwa kune pasi ndiro. Kudivi remberi, simbi yakatetepa ine chimiro chakananga inogadzirwa kuburikidza nephotolithography process seradiator. Chimiro cheplate inopenya inogona kuchinjwa nenzira dzakawanda maererano nezvinodiwa.
Kusimuka kweiyo microwave yekubatanidza tekinoroji uye maitiro matsva ekugadzira akakurudzira kuvandudzwa kwema microstrip antenna. Kuenzaniswa neantenna yechinyakare, microstrip antennas haisi madiki chete muhukuru, huremu huremu, yakaderera muchimiro, iri nyore kuenderana, nyore kubatanidza, yakaderera mumutengo, uye yakakodzera kugadzirwa kwehuwandu, asi zvakare ine zvakanakira zvakasiyana-siyana zvemagetsi emagetsi.
Iwo mana ekutanga ekudyisa nzira dze microstrip antenna ndeaya anotevera:
1. (Microstrip Feed): Iyi ndiyo imwe yenzira dzakajairika dzekudyisa ma microstrip antenna. Iyo RF siginecha inoendeswa kune inopenya chikamu cheantenna kuburikidza neiyo microstrip mutsara, kazhinji kuburikidza nekubatanidza pakati peiyo microstrip mutsara uye chigamba chinopenya. Iyi nzira iri nyore uye inoshanduka uye yakakodzera dhizaini yeakawanda microstrip antennas.
2. (Aperture-coupled Feed): Iyi nzira inoshandisa slots kana maburi pa microstrip antenna base plate kudyisa mutsetse we microstrip muchinhu chinopenya che antenna. Iyi nzira inogona kupa zvirinani impedance yekufananidza uye kugona kwemwaranzi, uye inogona zvakare kuderedza yakachinjika uye yakatwasuka danda upamhi hwepadivi lobes.
3. (Proximity Coupled Feed): Iyi nzira inoshandisa oscillator kana inductive element iri pedyo ne microstrip line kudyisa chiratidzo mu antenna. Iyo inogona kupa yakakwira impedance yekufananidza uye yakafara frequency bhendi, uye inokodzera dhizaini yehupamhi-bhendi antenna.
4. (Coaxial Feed): Iyi nzira inoshandisa coplanar waya kana coaxial tambo kudyisa masaini eRF muchikamu chinopenya cheantenna. Iyi nzira inowanzopa yakanaka impedance yekufananidza uye nemwaranzi kushanda zvakanaka, uye inonyanya kukodzera mamiriro ezvinhu panodiwa imwe antenna interface.
Nzira dzakasiyana dzekudyisa dzinozokanganisa iyo impedance yekufananidza, frequency maitiro, kugona kwemwaranzi uye chimiro chechimiro cheantenna.
Maitiro ekusarudza iyo coaxial feed point ye microstrip antenna
Paunenge uchigadzira microstrip antenna, kusarudza nzvimbo yecoaxial feed point kwakakosha kuti uve nechokwadi chekuita kweantenna. Hedzino dzimwe nzira dzakakurudzirwa dzekusarudza coaxial feed mapoinzi e microstrip antennas:
1. Symmetry: Edza kusarudza coaxial feed point iri pakati pemicrostrip antenna kuchengetedza symmetry yeantenna. Izvi zvinobatsira kuvandudza mashandiro emwaranzi yeantenna uye kuenzanisa kwekukanganisa.
2. Ipo nzvimbo yemagetsi ndiyo yakakura: Iyo coaxial feed point inosarudzwa zvakanyanya panzvimbo iyo nzvimbo yemagetsi ye microstrip antenna ndiyo yakakura, iyo inogona kuvandudza kushanda kwechikafu uye kuderedza kurasikirwa.
3. Iko ikozvino kwakanyanyisa: Iyo coaxial feed point inogona kusarudzwa padhuze nenzvimbo iyo ikozvino ye microstrip antenna inonyanyisa kuwana yakakwirira radiation simba uye kugona.
4. Zero electric field point in single mode: Mu microstrip antenna design, kana uchida kuwana single mode radiation, coaxial feed point inowanzosarudzwa pa zero electric field point in single mode kuti uwane zvirinani impedance inoenderana nemwaranzi. hunhu.
5. Frequency uye waveform analysis: Shandisa maturusi ekufananidza kuita frequency kutsvaira uye yemagetsi munda / ikozvino kugovera kuongororwa kuti uone iyo yakakwana coaxial feed point nzvimbo.
6. Funga nezve dhizaini dhizaini: Kana radiation maitiro ane chaiyo yakananga inodiwa, nzvimbo yeiyo coaxial feed point inogona kusarudzwa zvinoenderana negwara kutungamira kuti uwane inodiwa antenna radiation performance.
Mune chaiyo dhizaini dhizaini, zvinowanzodikanwa kusanganisa nzira dziri pamusoro uye kuona iyo yakakwana coaxial feed point chinzvimbo kuburikidza nekutevedzera ongororo uye chaiyo kuyerwa mhedzisiro kuti uwane zvinodikanwa zvekugadzira uye mashandiro ezviratidzo zve microstrip antenna. Panguva imwecheteyo, marudzi akasiyana e microstrip antennas (akadai sechigamba antennas, helical antennas, nezvimwewo) anogona kunge aine mamwe mafungidziro pakusarudza nzvimbo yecoaxial feed point, inoda kuongororwa uye optimization yakanangana neiyo chaiyo antenna mhando uye. application scenario. .
Musiyano uripo pakati pemicrostrip antenna uye chigamba antenna
Microstrip antenna uye chigamba antenna maviri akajairika madiki antenna. Vane zvimwe zvakasiyana uye maitiro:
1. Chimiro uye marongerwo:
-A microstrip antenna kazhinji ine microstrip chigamba uye pasi ndiro. Iyo microstrip patch inoshanda sechinhu chinopenya uye yakabatana neplate yepasi kuburikidza ne microstrip line.
- Patch antennas anowanzo kondakita zvigamba zvakamisikidzwa zvakananga pane dielectric substrate uye hazvidi mitsetse yemicrostrip senge microstrip antenna.
2. Saizi uye chimiro:
-Microstrip antennas idiki muhukuru, inowanzo shandiswa mumicrowave frequency band, uye ine dhizaini inoshanduka.
- Patch antennas inogona zvakare kugadzirwa kuti iite miniaturized, uye mune dzimwe nguva, hukuru hwayo hunogona kunge hudiki.
3. Frequency range:
- Iyo frequency renji ye microstrip antennas inogona kubva kumazana e megahertz kusvika akati wandei gigahertz, ine mamwe mabroadband maitiro.
- Patch antennas anowanzo kuve nekuita zvirinani mune yakatarwa frequency mabhendi uye anowanzo shandiswa mune chaiyo frequency application.
4. Nzira yekugadzira:
-Microstrip antennas anowanzo gadzirwa uchishandisa yakadhindwa yedunhu bhodhi tekinoroji, iyo inogona kuve yakawanda-yakagadzirwa uye ine mutengo wakaderera.
- Patch antennas anowanzo gadzirwa nesilicon-based zvinhu kana zvimwe zvakakosha zvinhu, zvine zvimwe zvinodikanwa zvekugadzirisa, uye zvakakodzerwa nediki batch kugadzirwa.
5. Polarization maitiro:
-Microstrip antennas inogona kugadzirwa mutsara polarization kana denderedzwa polarization, ichivapa imwe nhanho yekushanduka.
- Iyo polarization maitiro echigamba antennas anowanzoenderana nechimiro uye marongero eiyo antenna uye haina kuchinjika senge microstrip antennas.
Kazhinji, microstrip antennas uye chigamba antenna zvakasiyana muchimiro, frequency renji, uye maitiro ekugadzira. Kusarudza iyo yakakodzera antenna mhando inoda kuve yakavakirwa pane chaiyo application zvinodiwa uye magadzirirwo ekufunga.
